FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

For some weeks I have ad an issue with Firefox using 50%-100% of CPU. Normally it is the Firefox process itself, sometimes it is also "Privileged Cont".

OS is Kubuntu 24.04. Firefox has done this across 2-3 versions.

Things I have tried:

Restarting Firefox No change, I'll even get 100% cpu usage with no tabs open

Refresh Firefox to remove settings and addons No change

Uninstall Snap and try direct Apt package No change

Remove ~/.mozilla to fully remove any residual settings/cache/etc No change

Try with and without hardware acceleration See: https://support.mozilla.org/en-US/questions/1308215 No change!

I would blame my old computer hardware, but Brave runs fine. I am now using Brave, but would dearly like to return to Firefox as I miss containers, and I don't support a chromium dominated web.

Is there a way to just paste a file with path for uploading. In the windows dialogue I can do that to bypass waiting, but in the linux dialogue 1. I really have to wait for all folder content to be shown (I just tried that on a network drive with a quarter million images) 2. I cannot just type paths that are hidden but I know they exist

I updated firefox just yesterday or earlier today idk and the right click menu is so long with multiples of the same and they DO NoThInG! Linux Mint 22 Cin. 6.8.0-55 Generic Kernel

Firefox 136.0.1, Linux 6.8.0-55, have set Okular as default pdf application, however Firefox will not open pdf file when downloaded nor will it open the file when selecting Open File from the Download Icon on the toolbar. Only was I can get to file is to select Show in Folder option and open from within Dolphin.

apparently, programmers don't understand how aggravating not having backward compatibility is to the rest of us, so please bear with my extreme aggravation here. IF IT AIN'T BROKE, QUIT FIXING IT.

 firefox disabled my addons, thus forcing me to upgrade, and now I am angry. Tried downloading the new version several times. My os is as updated as it can get. Using the APT link from this site, it just shows garbage. Using the download for linux 64 bit link, it makes me jump through hoops and looks like it is working, but it looks different and none of my bookmarks transferred over. Closing it down and reopening it, I see the old version, thus making it look like I am possibly running both versions separately. Once the *all new singing and dancing special that is supposedly so much better than the old that some ignoramus decided I MUST use it instead of the old and functional one* is closed out, I see no way to reopen it. And neither version will enable or allow me to download singlefile. That is the only program I need from firefox at this time.
 Will somebody please show me, step by step, as if I am 5 years old, a back door that will enable my addons, before I go nuts and start beating programmers to death with reams of algorithms?

very frustrated, and pissed at how programmers always screw things up that are working just fine by upgrading crap. Now, I have suddenly had all of my addons quit working, was forced to update my firefox. Nothing changed, and it still shows that I am using version 105, instead of the all-new, better and fancier, singing and dancing crap that is being forced upon me.

If I display (e.g.) Nepal in Google maps, initially the Nepali names appear beneath the Latin alphabet names, but only for a split second. They are then overwritten with unicode block icons. Some scripts work (e.g. Cyrillic, Chinese, Japanese, Armenian), but most south Asian scripts do this weird "works for a split second" rendering.

I'm running 128.8.0esr (64-bit) on Debian 12.

This problem does NOT occur in Safe Mode!

In Normal mode, I disabled all plugins and extensions, but the rendering still breaks.

Any ideas?

The same page renders properly in Chrome 134.0.6998.88

snap version seems to have problem thought this might help. I am a software developer.

Here are the dpkg/apt logs for update:

The problem is that when I tried opening gmail in my ubuntu, it is stuck at loading page, but other browsers like edge can open it without any problem (on the same system).

I tried every thing I can in the support forum of gmail/mozilla/others, but it's still stuck at loading.

That's all.

I'm using Linux Mint cinnamon 22 and have the latest version of Firefox installed or updated from the app updates. Firefox was already installed and is my preferred browser. But i have the problem when i go to the settings page i see a message on top (picture attached with this post) that says "Your browser is manged by your organization".

Which is simply not true. This is my personal laptop and it belongs to me. I see an answer from Linux mint devs that they will take it up with Mozilla. But that was three years ago. Can this message be ignored or is it still the case? For peace of mind, how do i verify that something is not managing my device?

My linux system no longer has pulseaudio installed (for reasons unrelated to firefox).

The --enable-alsa option is not rejected by firefox but doesn't work either. The only way to get audio from firefox in this install is through the apulse wrapper:

    apulse firefox ...

Note that chrome browsers have no problem with audio when pulseaudio is not installed.

Is the --enable-alsa in firefox supposed to work?

thanks!

I use Firefox with DuckDuckGo on Ubuntu 24.04, Gnome desktop. My Firefox browser window regularly freezes but can be unfrozen by simply repositioning the window. This is really annoying.

I also use Chromium on the same system and there are no issues.

Any ideas?

The Firefox 'Downloads, Save Files To.." location appears to be disconnected from reality. If I indicate either of the Documents or Desktop folders as the preferred save location, both of those folders present as being empty when in fact they both have numerous files/directories. Even if I try to save in "+ Other Locations", those locations are limited to the same as presented in the 'Browse' window of Home, Desktop, Documents and Downloads. Only the Downloads folder displays correctly.

Also as a result of this limited save location, I can only retrieve a file from the Downloads folder (the attached file was saved in my Documents folder but I had to move it to Downloads.

Why does the saving behavior behave like this?

Hello, - Computer Nec Versa One P/N NNAN1700202 (32-bit) - XUbuntu 18.04.2LTS (i386), no upgrade possible to 19 LTS

- Message asking for an update of Firefox (expired root certificate, extensions disconnection) - Proposed download completed (Firefox 135.0)

- Firefox/ Help/ "About Firefox": 113.0.2 (32 bits), no update proposal - Launch the . exe file from previous download In the "About Firefox" window, version 135.0 appears well during installation When the computer is restarted, this panel has returned to version 113

The computer works normally and perfectly meets my needs (emails and internet searches), so it is out of the question to change it (it would be scandalous from an environmental point of view)

What should I do? Thank you for giving me the precise instructions on how to proceed. Sincerely, FC

Thought only Ubuntu's linux firefox 136.0 was 'unstable' on my Gateway E-475M laptop - crashes, restores session then freezes only to log me out, then completely locking up requiring holding down power button and rebooting...

NOW, even firefox 136.0 on WIN7 is crashing, then restores session only to go to the 'blue screen of death' requiring holding down the power button and rebooting...

EVIDENTLY, the problem is NOT with Ubuntu or WIN7, but either: firefox (linux or win version); or, the Gateway E-475M laptop (2.0GHz CPU, 4Gb RAM, 8Gb swapfile, Harddrive at 61% usage, linux/win on separate booting partitions, LAN + usb & pci wifi's, etc.) - both OS's USED to work fine, but as upgrades to firefox have come along, they have steadily gotten more and more unstable...

Sometime, I'm only making a bookmark, and it starts this circus act... does it on differing websites, etc. Firefox is the only thing loaded - using two windows on two different monitors.

...at a loss as to what to do - firefox is supposed to be THE lightest-weight browser out there, and was for awhile...

- - - - - the only extension used on both systems is NoScript - could THAT be causing the disturbance in the force?!?

Hi there, I updated Linux Mint today and now have a crash effecting access to Netflix. First time ever to occur. What is wrong and how do I fix it?
